SPRING-SHUTTLE BEATER FOR POWER-LOOMS.

Specification of Letters Patent.

Patented Mar. 21, 1911.

Application filed August 13, 1910. Serial No. 577,037.

To all whom it may concern:

Be it known that I, OTTO HALLENSLEBEN, a subject of the German Emperor, residing at 7 Hilgerstrasse, Gorlitz, Germany, have invented a certain new and useful Spring- Shuttle Beater for Power-Looms, of which the following is a specification.

The operation of the shuttle by means of a previously tensioned spring has the great advantage that during slow and rapid operation of the loom the shuttle is continuously picked with the same force. In order, however, that the loom may operate at the required speed, devices must be provided to withdraw the shuttle driver after striking from the shuttle box.

This invention relates to a device for immediately withdrawing the shuttle driver after each stroke. This is eflected in such manner that the picking spring, by the rotation of a suitable disk, is tensioned and the disk then looked. On the release of the disk which was previously rotated to tension the spring and on its return movement, due to the action of the tensioned spring, the disk rotates with it a second disk connected to the beating up mechanism by means of a free wheel coupling. In this manner on the retardation of the disk, connected to the picking spring, by the spring, the disk connected to the picking up mechanism is, in consequence of the momentum imparted thereto, moved beyond the picking up position whereupon on the completion of the revolution it is retained in the required position for the next operation by a pawl or the like. The simplest method of constructing such a shuttle picker device is to provide a disk which can be rotated into the required position by the mechanism of the loom and released by a pawl, which disk winds up a member connected to the picking-up spring and on its release by a pawl rotates a second disk which is connected to the picking-up mechanism and after a complete revolution is locked by a pawl which is adapted to be released by the mechanism of the loom.

In the accompanying drawing is illustrated a constructional form of the new shuttle heating device of which one disk operates one picker staff and the other disk, the other.

Figure l is a side elevation. Fig. 2 is a plan. Figs. 3 and 4 show a part of the picking mechanism in two positions which occur during the operation. Fig. 5 shows diagrammatically the application of the shuttle picking device to a loom. This only shows a particular example of the application of the invention, as this naturally can be applied in any other suitable manner.

On the shafts a, a are rotatably mounted toothed wheels 6 and c, and a toothed wheel cl secured to the wheel I) engages with a segment f oscillated by the mechanism 25 driven from the crank shaft 25 of the loom through the medium of the crank it and the connecting rod '0. The two toothed Wheels 6 and c are in engagement with one another so that the movement imparted to the toothed wheel 6 by the sector 7' is transmitted to the wheel 0. The toothed wheels 6 and c are provided with projections b and c which cooperate with projections g and h provided on disks 9 and 71., one for each picker staff 1), rotatably mounted on the shafts a, a so that on the rotation of the Wheels 6 and c in one direction the disks 9 and 72, are also rotated. The disks g and h are provided with cams g and 72, adapted to tension springs 2' 11 by means of chains 1' r secured to pins 9 and 71, carried by disks 9 and h and to the picking-up springs c; the said chains being wound on the respective cams on the rotation of the disks 9 and h. By winding the chains on the cams g and 71/ the springs z are tensioned. After the disk It (in Fig. 1) has been rotated through half a revolution for tensioning the springs, one of the pawls engages the projection on the disk, so that the disk is prevented from being rotated by the spring i. After the spring 6 has been tensioned in the manner hereinbefore described the pawl 70 is released by suitable mechanism operated by the mechanism of the loom at the moment that the picking-up is to be effected. The disk h when released, is then rotated in the opposite direction by the spring 2'.

IVhen the disk It is in the position shown in Fig. 1 that is in the position in which the picking-up spring z is tensioned, the disk 71, by means of a pawl Z engages with a projection provided on a disk m rotatably mounted on-the shaft a By means of pawl n which engages with a projection on the disk m the latter is held in the position shown in Fig. 1. In this figure the pawl is shown in the raised position whereas the disk m is still in the locked position. The pawls n and n are, of course, mounted on the frame of the machine in the customary way, as shown in Fig. 5.

On the shaft o which is rotated from the crank shaft 6 of the loom by the toothed wheels t and the bevel wheels t are mounted disks '0 provided with projections 41 and 41 These projections respectively operate upon pivoted levers n and respectively connected to the pawls n and 70 by the members n and 7%. The pawls 7a and n are mounted on the main frame of the machine.

It will be understood that a second set of disks of is mounted upon'the shaft '0 for operating through the medium of the similar mechanism the corresponding pawls controlling the mechanism on the shaft a For releasing the picking-up mechanism the pawl is is raised simultaneously or almost simultaneously with the pawl 02 whereupon an auxiliary pawl 0? comes under the latter and retains it in the disengaged position (Fig. 1). On releasing the pawl 70 the picking-up is effected and the disk It rotates by means of its pawl Z the disk m. 'In this manner the outwardly directed projection of the disk m abuts against the downwardly directed part of the auxiliary pawl n and puts this out of engagement, so that the pawl 1?. comes into contact with the periphery of the disk m (Fig. 3).

'By reason of the pulling action of the spring 2' the disk h, by means of the pawl Z, rotates the disk m, which is connected by means of the arms 0 to the picking-up arm 70, into the position shown in Fig. 3. In this position the disk 71, is retarded by means of the spring 2' which latter on further rotation of the disk It would be again'tensioned. The disk m, however, as its projection is released from the disk It, rotates further in consequence of its momentum, assisted by the spring 8 of the picking-up arm 29 (Fig. 1) so that the picking-up arm 3) is again drawn back by the rod 0. The rotation of the disk 11? is limited by the pawl a resting on the periphery of the said disk m, which pawl retains the disk m in the position shown in Fig. 1, and on rotating the disk It for the purpose of tensioning the spring 2', the pawl Z of the disk it moves over the inwardly turned projection of the disk at and engages behind this projection. The device isthen in the necessary position for the next beating-up operation.

The arrangement of the A two toothed wheels Z) and 0 is applicable to looms which re ularly and alternately beat up right and The devices cooperating with the wheel I) are exactly the same as those hereinbefore described cooperating ,with the toothed wheel 0. During two revolutions of the batten there is a single oscillation of the segment f, whereby the movement to the left tensions, when the one to the right effects the picking-up and vice versa.
